GEBA is the Genomic Encyclopedia of Bacteria and Archaea. They developed a strategy to select microbial genomes not because of some important physiology of that microbe, or because it was a disease-causing organism, but more based on looking across the world of species via phylogeny, and selecting some that might have been otherwise neglected. This is a neat strategy in many ways, because usually we only look under the flashlight for stuff we are kinda looking for already. This turns that around and looks in the dark as well. That does make it something of a fishing expedition, and I can understand those criticisms of an approach like that. But we are sure to learn useful things from stuff we weren’t really looking for too.
